>Rebooting means booting the system again.  This can be
	accomplished by first shutting it down completely, turning
	power off, and then turning it back on.  A simpler way is to
	ask <B
CLASS="COMMAND"
>shutdown</B
> to reboot the system, instead
	of merely halting it.  This is accomplished by using the
	<TT
CLASS="OPTION"
>-r</TT
> option to <B
CLASS="COMMAND"
>shutdown</B
>,
	for example, by giving the command <B
CLASS="COMMAND"
>shutdown -r
	now</B
>.</P
><P
>Most Linux systems run <B
CLASS="COMMAND"
>shutdown -r now</B
>
	when ctrl-alt-del is pressed on the keyboard.  This reboots the
	system.  The action on ctrl-alt-del is configurable, however, and
	it might be better to allow for some delay before the reboot on
	a multiuser machine.  Systems that are physically accessible to
	anyone might even be configured to do nothing when ctrl-alt-del
	is pressed.  </P
